Abstract

The current stage of development of the construction industry of Ukraine and foreign countries contains the direction to extend the life of the operated construction projects. This direction is directly related to the research of physical and mechanical characteristics of concrete as the main building material. A significant number of such studies can be performed using the ultrasonic pulse method. But despite its potential practice shows the insufficient level of use of this method. Thus, this method, in addition to determining the strength of concrete, allows to determine its characteristics such as the level of crack formation, geometric parameters of the planes of stratification in monolithic concrete, and the like. The system analysis of technical characteristics of serial ultrasonic devices that are produced in Ukraine and foreign countries is carried out. The results of the analysis revealed that their technical characteristics allow measurements, mainly to determine the strength, uniformity of concrete. These devices also do not allow to measure vibration, noise and electrical interference, which is typical for production conditions. The conducted researches allowed to reveal the main directions of improvement of serial ultrasonic devices, Metrology. This allows us to solve the problem of expanding the application of this method in the practice of non-destructive testing of physical and mechanical characteristics of concrete operated construction projects.
